A LettersPatent No. 95,913,lated October 19, 1869.

IMPROVED ROTARY VEG-ETABLE-G-RATER.

The Schedule referred to in these Letters Patent and making parl: of the sama.

To all whom it may concern:

Be it known that I, WILLIAM E. KNIGHT, of Shrewsbury, in the county of Rutland, and State of Vermont, have invented a new and useful Improvement in Vegetable-Grateis; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a longitudinal side elevation, with a part ofv curb removed.

Figure 2 is an elevated end and face view of' grater.

Figure 3 is a longitudinal vertical view, with part of curb removed. j

Figure 4 is an end elevation and back View of grater.

The nature of my invention consists in combining, with a revolving perforated grater, disk, or plate,.a feed-mechanism, consisting of a sliding carriage, moving on ways or guides, at right angles with the face of grater, said carriage being made to travel toward the face ofthe grater by means of a weight, cord, and pulleys, and the whole so constructed as to allow it to be secured to the edge of a shelf', table, or any convenient projection, and is particularly intended for household and family-use.

To enable others skilled in the art to make and use my invention, I will proceed to give a description of its constiuction and operation.

A is bed-frame of machine.

D is a shaft, supported in bearings in the standard B, and Vhead-block O.

Said shaft carries, near its outer end, a hub, H, to which is attached a circular metallic plate or disk, Z, theface of which has numerous perforations, made by driving a pointed instrument through it from the -back side, in the well-known manner of making graters Y of metal plates.

To the other end of the hub H are attached four arms, c.

To these arms are attached four small hubs or studs, xxxx.

Said small hubs are also secured to the grater-plate near its outer edge, for the purpose of giving` greater strength and stability to the same.

on is a handle attached to one of the arms e', for

the purpose of communicating motion to the grater.

O is a curb attached to the head-block O, and eneircles nearly three-fourths of the circumference ofthe grater-disk, leaving an open space on under side. This curb is for the purpose of preventing the grated suhstance from flying olf, by confining itto the inside, while the opening at the bottom allows it to drop into a vessel placed to receive the same.

E is thecarriage-bed attached to bedr-frame A, and furnished with grooves, g,-on its sides, to receive the. lips or flanges d of sliding carriage F, `which works in same.

t is a point or spur attached to upright part of sliding carriage F. Said point is for the purpose of keeping one end of the vegetable in proper position While the other end is heilig operated upon by the grater.

S is a cord attached to the sliding carriage F.

Said cord passes around and over the pulleys a b', with a weight, W', attached to lower end, as shown in figs. 1, 2, and 3. A circular opening is made in the head-block C, to allow the vegetable to pass through and hold the same imposition While being acted upon by the grater. v

The drawings represent the machine attached to a table, T, by a screw-clamp, AV, but any other convenient means can be used for the purpose.

The operation of the machine is as follows:

Vhen the sliding carriage F is drawn back from face of gratcr Z,a sutlicient distance to receive the vegetable, and the spur or point t' pressed into end of same, the other end resting in and passing through the circular opening in head-block C, the machine is ready for operation.

B y turning the handle on in the direction represented by the arrows in figs. 2 and 4, the shaft D, with its grater Z, is made to revolve, and its rough surface acting on the vegetable, grates or cuts it awa the weight- W causes the sliding carriage F to advance, pressing the vegetable against the face of grater until it is quite or nearly all gra-ted away, when the sliding carriage is again drawn back, another vegetable placed in position, and the operation is repeated.

What I claim as my invention, and desire to secure by Letters Patent, is-.

The combination of the revolving disk-grater Z, with a slidingA carriage, F, for feeding the vegetable up to the grater, by means of the Weight W, cord S,

- pulleys a and b', or their equivalents, substantially as and for the purposes specified.
